Shawty: URL Shortener Service

This service encodes URL in base-36 and store them in filesystem.

It has 3 features: shorten, unshorten, and redirect.

Can I use it in production?

You need to implement a storage that can scale beyond one application server.

Why?

By itself, URL shortening is quite useful.

But this project exists to demonstrate:

• How concise Go is. cloc shows that this project contains only 125 lines.

• How slim Go is: 3MB RAM.

• How comprehensive Go standard library is.

• How easy it is to get up and running in Go. It took me about 1 hour from start to finish. Writing this README file took longer time.

• How performant Go is:
